A TTORNEYS Patented Aug. 11, 1931 UNIE STATES PATENT b FH E EDWIN A.GLLEY, OF SYRACUSE, NEW YORK,.ASSIG-NOR TO CRGUSE-HINDS CGEl-LPl-iNY, 0FSYRACUSE, HEW YGHK, A GORPGRA'IION OE NIVV YGRK WALL COVER PLATE ANDMOUNTING THEREFOR Application filed. September This invention has forits object a particularly simple and eflicient means for closingopenings in walls, or what for the sake of convenience I have called anaccess opening 5 cover which can be readily installed and the coverplate thereof readily removed and replaced.

The invention consists in the novel features and in the combinations andconstructions l0 hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanyingdrawings in which like characters designate corresponding parts in allthe views.

Figure 1 is an edge View of this access opening cover, the contiguouspart of the wall structure being also shown.

Figure 2 is a plan View of parts seen in Figure 1.

Figure 3 is a perspective View of this cover, the contiguous portions ofa wall being also shown.

Figure 4 is a view similar to Figure 3 showing the cover from theopposite side of that shown in Figure 3.

Figure 5 is .an enlarged fragmentary View with contiguous portion of thewall structure being shown.

Figure 6 is a detail view of a portion of the fastening means selfcontained with the plate.

Figure 7 is a fragmentary plan View illustrating the fastening means.

In building structures, it has become quite common practice to build afalse wall or a double wall and to locate electric conduits, wires andother piping in the space behind the false wall and in order to haveaccess to the space behind the wall, it is necessary to have an opening,although .at the time the wall is built, the location of the opening maynot have been definitely determined. Some of the piping behind the wallmay have valves to which access must be had.

This invention relates to means for providing a cover and mounting forsuch openings.

The invention consists of a marignal frame 1 here shown as rectangularin general form and confining a rectangular opening and a e, 1929.Serial No. 390,320.

detachable cover plate 2. The mounting forms a facing for the edge ofthe wall .V e:-: posed in the opening in which the mounting is placedand has an outwardly extending flange 3 which is engaged with andsecured to the inner faceof the margin of the wall W It may be securedto-the rear side of the laths to which the plaster of the wall isapplied or to the framing asthe two by'fours of'thewall. In anycase,ithe flange 3 pmvides means for securing the mounting to the wall.

The cover plate 2 which lies substantially flush with the outer wall lVhas a marginal flange 4 opposing the flange 3 and forming a channel inwhich the margin of the wall lVis located. The cover is secured to themounting by fastening means self-contained therewith and coasting withthe mounting and here shown as coacting with an upwardly extendingmarginal flange 5 at the front end of the mounting. This flange 5overhangs the opening confined by the mounting.

The fastening means as here shown includes a screw 6 having its head 7exposed on the outside of the cover, the screw extending through thecover and threading into a nut 8 having an outwardly extending arm 9which when the screw is turned swings under or behind the fiange 5 andclamps against the flange'5. The nut 8 is here shown as provided witha'follower or pin 10 which is located in a guideslot 11 formed in abracket 12 projecting from the inner side of the cover plate 2. The slot11 has a straight portion parallel to the screw and an angular camportion 13 at the end of the straight portion nearest the cover plate. Acompression spring 14: is interposed between the nut 8 and the coverplate. Any number of fastening devices may be employed and as here shownthere are four of such devices.

In operation, when the cover plate is placed in position, the followeror pin 10 is at the remote end of the slot 10 and during turning of thescrew, the nut 8, as it cannot turn, feeds up the screw toward the coverplate and as it approaches the cover plate, it reaches the angularportion 13 of the slot 11 so that the turning of the screw swings thearm 9 of the nut 8 around under the flange 5 and continued turningaction tightens the arm 9 against the flange and securely clamps thecover plate to the mounting.

The specific construction of the fastening device forms no part of thisinvention and it is of importance insofar as it is sel'fcontained in thecover plate. O ing to the construction of the mounting and the coverplate, the mounting can be readily placed in position in the opening andthereafter the COYGl plate readily applied and removed.

hat I claim is 1. The combination of a mounting in the form of amarginal frame confining an opening, said frame having a body portionconstituting a lining for the edge face around an opening in a wall orpartition out a building, an outwardly extending flange at the inner ndof the body for lanpingand securementto the wall around the opening, andan inwardly extending flange overhanging the opening cou lined by theframe and a cover plate having means selt'contained therewith on the'nner side thereof for c acting with the inwardly extending iiange forsecuring the cover plate on the mounting, said securing means having anoperating member exposed on the outer side of the cover plate, the coverplate having a flange extending laterally beyond the body of themounting and together with the outwardly extending flange of themounting forming a channel in which the margin of the wall extends.

2. he combination of a mounting comprising a body in the form of amarginal frame forming the facing for the edge of a wall exposed at theopening in the wall in which the mounting is placed, the mounting havinga laterally extending flange at the inner side of the wall for lappingand secureinent to the wall, a cover plate for closing the openingconfined by the mounting, said plate having means selt'containedtherewith tor coacting with the mounting for securing the cover plate inposition, the cover plate having an outwardly extending marginal flangeopposed to the flange of the mounting and tormin g a channel. forreceiving the margin of the wall in which the mounting is placed.

In testimony whereof, I have hereunto signed my name, at Syracuse, inthe county of Onondaga, and Sta te oi New York, this 17th day oi August,1999.
